Yu Na won in Vancouver over a mistake prone Mao by 23, both getting inflated scores. Mao skated a great program at world's, with only a 3A<, yet scored lower than Vancouver, 197 without the Vancouver inflation. Yu Na had a mistake filled Sp and FS, yet was somehow was awarded a win in the FS over Mao by 131 to 129. The audience just scratched their heads, wondering why.Yu Na from Vancouver would have won the 2010 Worlds by about 40 points, and Yu Na from virtually every competition the 3 years preceding Vancouver would have won the 2010 Worlds by over 20 points. A silver medal in such a poor Worlds as proved by an only 5 triple Ando who can do absolutely NOTHING but jump winning those Worlds.
